In one embodiment the catheter device comprises a flexible tube having a port at the proximal end and a rounded closed tip and an aperture away from the tip at the distal end. A diaphragm having a hole through which the tube may pass is used to seal off the cervix and upper vagina from the lower vagina, and a syringe is used to administer the pharmaceutical material through the port in the flexible tube. In a second embodiment two ports are provided in the flexible tube, enabling a flushing material to be ejected into the tube after the pharmaceutical material, thus ensuring that the entire dose of pharmaceutical material is delivered to the cervix and the upper vagina.Field of SearchNozzle insertable into body orificeHaving external means for receiving material discharged from body orifice Colostomy apparatus Having orifice sealing means Vaginal or douche type Having branched shapes (e.g., T or Y drains, etc.) ARTIFICIAL INSEMINATION Pessaries External supporters Inflatable Diaphragm Inserters and removers Intrauterine Inserters and removers With cervical cap | |
